. MACHINE FOR FINISHING ARTICLES OF GLASS'WARE.

SPECIFICATION forming part of Letters Patent No. 363,580, dated May 24, 1887. I

Application filed February 23, ISz'G. Serial No. M1928. (No model.)

To all whoin/ t 17mg/ concern.-

Be it known that we, JOSEPH E. BLACK BURN, of Vtheeling, in the county of Ohio and State of West Virginia, and WILLIAM l. MANN, of Benwood, in the county of Marshall and State of Vest Virginia, have invented a new and useful Improvement in Machines for Finishing Articles of Glassware; and we do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the lctters of reference marked thereon.

Nearly all articles of pressed glassware, particularly such as have a stem and foot, after being removed from the in old and reheated for the purpose of polishing and iinishing, frequently become so hot and pliable as to lose their shape unless provision is made to pievent it. This has heretofore been provided against by rolling the article over and over upon a smooth surface, and at the saine time the article has been polished and otherwise completed by proper manipulations with a hand-tool.

Our object is to provide a machine for polishing and finishing the article, and at thesanie time one which will prevent :its loss of shape from an excessive application of heat. These objects are very successfully accomplished by our present machine, which embraces a rotating former for'holding the article to be finished, an automatically-vibrating hook or guide, which fits partly around the stem of the article and keeps it straight or straightens it if crooked, and an automatical1y-vibrating buffer-holder carrying an adjustable buffer or iinishing and polishing tool,the said buffer-holder and the hook or guide operating simultaneously and at regular intervals in this waythat when one article is finished they both open or break contact with the same and allow it to be removed and another to be replaced before they again close in upon the former. In these several devices, together with their details of construction and arrangement, lies the novelty of our invention, for a more thorough understanding of which attention is invited to the accompanying drawings, in whichl Figure 1 is a plan view of the machine with various parts in dotted lines; Fig. 2, avertical longitudinal section of the same on the line a; a' ot' Fig. l, with several of the parts shown in full 5 Fig. 3, a vertical transverse section on the line g/ y, with several of the parts shown in full; and Fig. 4, a detail showing a portion "of the table and the way it is supported.

Like letters of reference denote corresponding parts in the several views.

A denotes a table, supported at its corners by suitable legs or standards, a, preferably of angular form, and secured to the table by bolts or rivets, as shown in Fig. 4.

B is the vertical main or driving shaft,\vliich passes through a tubular extension, b, of the table, and has a flange or collar, b, near its center, which sets upon the upper end of said extension b and maintains the shaft in proper position. A formen B', is screwed on the upper end of this shaft, so as to be removable to allow others of various sizes to be employed, and said former is used to liold the article While it is being polished and finished up.

The former should fit the interior of the article closely enough to turn it rapidly; but even if it fails to fit in this way its centrifugal force will be suiiicient to throw the sides of the article out against the buffer or polishing and finishing tool, presently to be described. Furthermore, the former may be of any size and shape suitable to accommodate the article to be worked on, and in Fig. 2 is shown as holding a glass goblet with its stem pointing upward, and in this position all articles are to be placed over the former.

In a straight line back of the shaft B, which carries the former, is another shaft, C, whichV passes vertically through a tubular extension, c, of the table, and has aiiange or collar, c', which sets upon the upper end of said extension and maintains the position of said shaft like as beforedesoribed with relation to shaft B. This shaft O carries near its upper end a A,

verticallyadjustable arm, C', adapted to be adjusted and secured by means of a suitable set-screw. This arm extends out laterally from its shaft, and its outer or free end is cast or otherwise provided with a hook or guide, G2, which may be adjustable upon the arm, and is slotted to receive and fit partly around the adjusted and secured by means of a suitableset-screw. Aside from the vertical adjustment, this buffer-holder D', as well as the arm C on the shaft C, previously described, may be capable of adjust-ment around their respective shafts, to accommodate large and small sized articles. This buffer-holder, like the arm C', extends out laterally from its shaft toward the former B', and is provided with a buffer" or polishing and finishing tool, D, adjustable longitudinally by means of a slot and setscrew.

To the lowerend of the main or driving shaft B is keyed a small conepnlley, E, which, by means of a proper belt-connection, drives a large cone -wheel, E, arranged horizontally under the table A and supported by a shaft screwed into a socket of the table at a point in the rear of the shaft C and central there with. This cone-wheel E holds a position reverse to that of the driving cone-pulley E, and has at its center, on the upper side, a small grooved pulley, e, which by proper belt connections transmits motion to the large grooved wheel E2, that is arranged horizontally under the table to the right of the shaft D, and is supported by a shaft screwed into a socket of the table at a point on a line straight and central with the shafts B and D. The upper face of this Wheel El has a tingershaped cam, F, which extends out laterally from the hub to the rim, and in every revolution of the wheel Ez makes contact with another cam, F, made rigid with the shaft D of the buffer-holder below the table A by means of a suitable set-screw. This cam F hasv an arm or extensiomf, which is pivoted at its outer end between the outer ends of a double lever, G, in turn jointed loosely to a lever, G', which is made rigid with the shaft C below the table A by means of a suitable set-screw.

H is a vertically and annularly adjustablev fork mounted on a vertical shaft, 71, screwed into a socket on the under side of the table at a point near one end of the latter and about midway between its sideredges, as shown in Fig. 1. This fork is provided to hold the belt in proper position upon the drivingpulley E made conical, in order to change the ratio of speed between the main shaft B and the wheel E2, for in working small ware thelatter should not run so slowly nor the shaft B so fast as when working large ware.

The operation of the machine is as follows: The driving-pulley E takes power from any suitablyarranged counter-shaft, and motion is transmitted tothe wheel E, and from thence tothe wheel E2. On the engagement of the cams F and F the shaft D is turned so that the buffer D2 is released from contactwith thesides of the article, aud-at the same time, through the medium of the levers G and G', the shaft G is turned so as to release the hook or guide CAZ from the stem of the article, and thus it is that both the buffer and the hook or guide open outward simultaneously and allow the finished article to be removed from the former and another article substituted in ils place. When the cams disengage themselves, the hook or guide and the buffer close in upon the newly-mounted article through the medium of a spiral spring, l, attached to the cam F" and to the table 'A at suitable points. The operations of thcsedcvices take place at regir lar intervals during the revolution of the wheel El.

The advantage asserted for our improved machine is that it will do the work of polishing and finishing more satisfactory and in less than half the time and with half the labor and expense heretofore required for such work.

What we claim as new, and desire to secure by Letters Patent, is*
